Application February 27, 1 943, Serial No. 477,431) (crest- 263) My invention relates to an improvement in 15 Claims.

storm window fastener, wherein it is desired to provide a fastener for pivoted windows, such as storm windows and the :like.

Various types of window fasteners have .previously been constructed and "such devices are in common use. It is the object of the present invention to provide a fastener of the same general type as has been previously constructed, but so devised that thef'astener is noiseless in "operation and will not rattle when in use.

A feature of the present invention lies in the provision of elongated leaf springs which are connected to the pivoted arm's fonn ing the window fastener. These springs are so arranged at the pivot points that the pivots are at 'all times under spring tension. As a result the rastener can not rattle or come lo'ose 'at the pivot points.

A feature of the prefer-red form of my invention lies in the provision of two ahgmany elements which are pivotally connected together at one end. These angularly shaped elements are so arranged that they provide a locking means for locking the arms inp'a-rallel relationship when it is so desired. The flanges are also so arra" "ed that they abut when the arms are swung into longitudinal alignment, thereby limiting the pivotal movement of the arms.

A feature of the referred form of my invention lies in the provision of elongated spring the pivoted arm-s. With such a construction the spring leaves may serve not only to maintain the pivotal connection between the'two arms uhder spring tension, but also these springs "serve between the respective arms and the window and window I der spring tension.

A further feature of the present invention lies in the manner in which one of the spring arms may be detached from its cooperabl'e bracket mounted on the window or the window frame. With such a construction the fastener may be detached from either the window '01" the indow frame to permit the window to be removed from its frame. 1 p

These and other objects and novel features of my'invention will be more clearly and fully set forth in the foll'owing specification and claims.

The w-i-ndow fastener A is designed to connect a pivotally hung window such as B to a window frame such as G. The window B is usually pivleaves which extend substantially the length or oted on a horizontal axis at the top of the window and the window may swing outwardly at itslower end an amount regulated by the fastener A. Oh-

viously th fastener A could similarly be used on I windows or the like supported on a vertical axis. The fastener A includes a pair of fastener arms H! and H which are pivotally connected by any suitable pivot m'eans such as the rivet l2. ihe pivotal connection between the two arms I!) and H is bestillustrated in Figure 5 of the drawing, which will be later described. n

The arm IO includes an elongated flat strip l3 having rounded ends l4 and I5. Apertu-res l6 and l! are provided in the ends M and I5 respectively. A flange l9 extends along one edge of th strip I3 at substantially right to, best illustrated in Figures '1 and 2 mg. v

The arm H is similar in of the drawv w 1' form to the arm I!) comprising a flat strip 20 having rounded ends 2i and Z2. Apertures 23 and'24respectively are provided in the ends of the strip 20. A flange 25 extends longitudinallythroughout the length of the straight portion of the strip edge 20, as best illustrated in Figures -1, 2, and 4 of the drawmg.

Leaf springs are provided extending longitudinally of the arms I0 and ll. A leaf spring 26 extends along the arm Ill adjacent the strip 13 When not fastened in place this leaf spring is bowed in such a mannerthat the center of the spring would contact the strip -l3 while the ends thereof w an be spaced from the ends of the strip l3. However, when thefastener is assembled the spring 26 extends substantialh parallel to the 'strip 13.

angles there- 4 window frame C and the shank "of extends through a'washer 45, through the off-set lustrated so as to normally touch the strip 26 near the center thereof and to be spaced from this strip at the ends of the spring. However, as illustrated in Figure 2 of th drawing one end of the spring 21 is secured closely adjacent the .end 2| of the strip while the other end thereof scribed. The pivot I2 is preferably in the form of a rivet having a shank 29 anda head 36. The shank 29 extends through a washer 3|,

The bracket 49 is provided with a base 54 designed for attachment to the window B by screws 55 or other suitable means. A right angular flange 56 extends upwardly from the base 54 designed to extend at right angles to the base. A circular area 51 of this flange 56 is recessed or off-set from the surface of the flange 56 and this circular area 51 is of just the proper size to receive the head 52 of the rivet 5|. A slot 59 extending inwardly from the edge of the flange 55 to the center of the circular area 51' is designed to receive the shank 53 of the rivet 5| to permit the head 52 thereof to engage the recessed area through the aperture 23 in .the arm H, through.

an aperture 32 in the spring 21, through the washers 33 and 34, through the aperture 35 in the spring leaf 26, through the aperture H in r the arm l9, and through a rectangular aperture 36 in the washer 31. The end of the shank 29 of the rivet I2 is then riveted over, deforming the end of the shank so that the rivet turns with the washer 31. This construction is designed to prevent the riveted end of the shank 29 from rotating relative to the'washer31 thereby weakening this relatively weaker connection.

A stile plate 39 is designed for attachment by screws 40 or othersuitable means to'the window frame C. This stile 'plate 39 is preferably formed U as illustrated in Figures 1 and 2 of the drawing, including aligned ends 4| and an oif-set central portion 42. A rivet 43 has its head-44 between this off-set portion 42 of the stile'plate and the the rivet 43 stile plate portion 42, a washer'46, the aperture IS in the arm l0, and a rectangular aperture 41 in the spring leaf26. The end of the rivet shank is deformed so that the'rivet'will be held from .rotation relative to the spring'leaf 26 and consequently relative to the arm Hi. "The shape of the spring leaf is such as to urgethestrip l3 of the arm l9 against the washer 46 and simultaneously to urge the washer against the underside of the off-set portion 42 of the stile plate 39,

therefore atight frictionjoint is maintained between the stile plate 39' and-the bracket arm ill.

Thespring arms 26 and 21 likewise provide continuous friction at the knee" joint orpivot l2. The spring leaves 26 and '21' tend to urge the yanns l9 and H against thewashers 31 and 3| respectively. At'the same time th washers 33 and 34 are being held between thesprings 26 and 21 under spring tension. To increase the friction effect'the washers 3|, 33, and 34 are provided with a rim portion which is thicker than the remainder of the washer to insure contact at the rim of the various washers.

The removable connection between the arm H and the bracket 49 will be best understood from an examination of Figures 2, 6, and '7 of the drawing. The spring leaf 21 is provided with a'rectangularaperture 59 therethrough designed to accommodatethe end of a rivet 5|. The rivet 5| is providedwith a head 52 and a'shank I 53. The end of the shank 53 is deformed so that no rotation can take place between the spring toward thestrip 2|] so that the head 52 may be engaged ina suitable receivingsocket in the V bracket 49.

circular area 51 in the flange 56. The spring 21 leaf 21 and the rivet 5|. The spring tension of is then released and the head 52 is pulled into the recess 51.

The tension of the springs 26 and 21 may be varied to suit various conditions, but ordinarily this tensionis so great that the spring 21 can not be urged toward the strip 20 with the fingers. The fastene is usually attached and detached by springing the spring 21 toward'the arm 29 with the aid of pliers, the head 52 beingreadily removable from the socket 51 in such a condi- 1 tion.

In the drawing the slot 59 is shown extending at substantially right angles from the base plate 54- of the bracket 49. Obviously this slot 59 could-enter the socket 51 from another direction, it being possible fo this slottoextend substantially parallel'to the base 54 if it is so desired.

I havefound that thespring tension of the spring 21 is sufiicient to hold the rivet head 52 in its socket. However, if the tension of the spring 21 is decreased somewhat it may be desirable to lock the slot 59 in a somewhat diiferent manner and so as to enter the circular area 51 from a somewhat different angle from that iilustrated.

,5! is coaxial with the'pivot 43. By swinging the arms I6 and H in unison about their respective pivots until the arms extend vertically upwardly from the pivots 43 and 5|, the window will be locked from outward movement by the flanges.

Furthermore the flanges l9 and 25 act to limit relative pivotal movementbetween the arms l6 and II. As shown in Figure l of the drawin ends 60 and 6| of the flanges l9 and 25 respectively are positioned soasto abut when the arms l0 and H are aligned, thereby preventing the two arms from swinging past aligned position;
